Using automated replacement with sed and editing I have now replaced all
occurrences of close() with VIR_(FORCE_)CLOSE() except for one, of
course. Some replacements were straight forward, others I needed to pay
attention. I hope I payed attention in all the right places... Please
have a look. This should have at least solved one more double-close
error.
* src/xen/xen_hypervisor.c (MAX_VIRT_CPUS): Move...
* src/xen/xen_driver.h (MAX_VIRT_CPUS): ...so all xen code can see
same value.
* src/xen/xend_internal.c (sexpr_to_xend_domain_info)
(xenDaemonDomainGetVcpusFlags, xenDaemonParseSxpr)
(xenDaemonFormatSxpr): Work if MAX_VIRT_CPUS is 64 on a platform
where long is 64-bits.
* src/xen/xm_internal.c (xenXMDomainConfigParse)
(xenXMDomainConfigFormat): Likewise.
Doing `virsh schedinfo rhel5u3 --cap 65535' the hypervisor does the
call, but does not change the value nor raise an error. Best is just to
consider it's not in the allowed values. The problem is that the error
won't be output since the xend driver will then be called and raise an
error
error: this function is not supported by the hypervisor: unsupported
in xendConfigVersion < 4
which will override the useful information from
xenUnifiedDomainSetSchedulerParameters(). So best is to also invert the
order in which the xen sub-drivers are called.
* src/xen/xen_hypervisor.c: mark 65535 cap value as out of bound
* src/xen/xen_hypervisor.c: reverse the order of the calls to the xen
sub drivers to get the error message if needed
All <console> devices now export a <target> type attribute. QEMU defaults
to 'serial', UML defaults to 'uml, xen can be either 'serial' or 'xen'
depending on fullvirt. Understandably there is lots of test fallout.
This will be used to differentiate between a serial vs. virtio console for
QEMU.

To allow the new virDomainUpdateDeviceFlags() API to be universally
used with all drivers, this patch adds an impl to all the current
drivers which support CDROM or Floppy disk media change via the
current virDomainAttachDeviceFlags API
* src/qemu/qemu_driver.c, src/vbox/vbox_tmpl.c,
src/xen/proxy_internal.c, src/xen/xen_driver.c,
src/xen/xend_internal.c: Implement media change via the
virDomainUpdateDeviceFlags API
* src/xen/xen_driver.h, src/xen/xen_hypervisor.c,
src/xen/xen_inotify.c, src/xen/xm_internal.c,
src/xen/xs_internal.c: Stubs for Xen driver entry points
* src/xen/xen_hypervisor.c: Remove all "domain == NULL" tests.
* src/xen/xen_hypervisor.h: Instead, use ATTRIBUTE_NONNULL to
mark each "domain" parameter as "known always to be non-NULL".
xen-unstable c/s 20762 bumped XEN_SYSCTL_INTERFACE_VERSION to 7. The
interface change does not affect libvirt, other than xenHypervisorInit()
failing since version 7 is not tried.
The attached patch accommodates the upcoming Xen 4.0 release by checking
for XEN_SYSCTL_INTERFACE_VERSION 7. If found, it sets
XEN_DOMCTL_INTERFACE_VERSION to 6, which is also new to Xen 4.0.
xen-unstable c/s 20685 changed the domctl interface, adding a field to
xen_domctl_getdomaininfo structure. This additional field causes stack
corruption in libvirt. xen-unstable c/s 20711 rightly bumped the domctl
interface version so it is at least possible to handle the new field.
This change accounts for shr_pages field added to xen_domctl_getdomaininfo
structure.
When querying about a domain from 0.3.3 (or RHEL 5.3) domain located
on a 0.6.3 (RHEL-5) machine, the errors are not properly reported.
This patch from Olivier Fourdan <ofourdan@redhat.com> , slightly
modified to not change the semantic when the domain os details cannot
be provided
* src/xen/proxy_internal.c src/xen/xen_hypervisor.c: add some missing
error reports
* src/xen/xen_hypervisor.c: xen-unstable changeset 19788 removed
MAX_VIRT_CPUS from public headers, breaking compilation of libvirt
on -unstable. Its semanitc was retained with XEN_LEGACY_MAX_VCPUS.
Ensure MAX_VIRT_CPUS is defined accordingly.
The xenstore database sometimes has stale domain IDs which are not
present in the hypervisor anymore. Filter these out to avoid causing
confusion
* src/xen/xs_internal.c: Filter domain IDs against HV's list
* src/xen/xen_hypervisor.h, src/xen/xen_hypervisor.c: Add new
xenHypervisorHasDomain() method for checking ID validity
- Don't duplicate SystemError
- Use proper error code in domain_conf
- Fix a broken error call in qemu_conf
- Don't use VIR_ERR_ERROR in security driver (isn't a valid code in this case)
Add the virStrncpy function, which takes a dst string, source string,
the number of bytes to copy and the number of bytes available in the
dest string. If the source string is too large to fit into the
destination string, including the \0 byte, then no data is copied and
the function returns NULL. Otherwise, this function copies n bytes
from source into dst, including the \0, and returns a pointer to the
dst string. This function is intended to replace all unsafe uses
of strncpy in the code base, since strncpy does *not* guarantee that
the buffer terminates with a \0.
